Help me downgrade my PSP please

[Benarbia]

I have the old style PHAT PSP with the latest Sony firmware on it.

I would like to downgrade it to 1.50.

Can someone give me a step by step guide to making it happen.

Thank you

I have a pandora battery but it doesn't want to charge, I'm thinking it only works with the slim PSP

Just plug your PSP into the wall so that it gets the energy from the AC adapter. Then put the pandora battery into your psp.
